An extension of the Flutter Material Slider to allow selection of a range of values via 2 thumbs.
Step by step explanation
A full explanation on how to build such Widget may be found on my blog:
You should ensure that you add the following dependency in your Flutter project.
dependencies: flutter_range_slider: "^1.5.0"
You should then run
flutter packages upgrade or update your packages in IntelliJ.
In your Dart code, to use it:
import 'package:flutter_range_slider/flutter_range_slider.dart' as frs;
> As of version 1.7, Flutter Framework also has its own RangeSlider. > If you want to keep working with this library, you need to import the package, using an alias e.g. frs. > Then, your need to prefix both RangeSlider and RangeSliderCallback with this alias (frs.RangeSlider and frs.RangeSliderCallback)
An example can be found in the
example folder. Check it out.
